When the four insulating edge wheels 7 are respectively in contact with the side walls of the building gutter 1, the mobile platform 3 can only move along the wall route at this time.

[0034] A cutting assembly is provided to cut the metal roof eaves 2 on both sides or one side. The cutting assembly is arranged on four supporting columns 4 through an installation assembly. The installation assembly includes a cutting mounting frame 8 and an auxiliary connecting seat 15. The cutting assembly includes a T-shaped swing arm 10 and two cutting control boxes 12. A second height fixing nut is inserted into one side of the cutting mounting frame 8 that is sleeved with four supporting columns 4, and a reference bearing seat 9 is provided at the upper end of both sides of the cutting mounting frame 8. The T-shaped swing arm 10 includes a cross bar and a downward pressure rod, and two reference bearing seats 9 are respectively inserted in the two sides of the cross bar through bearing rotation. A cutting mounting beam 11 is horizontally provided at the lower end of one side of the downward pressure rod of the T-shaped swing arm 10 through a mounting rod, and two cutting control boxes 12 are respectively vertically arranged on both sides of the cutting mounting beam 11 through clamps. A cutting disk 13 is provided on the side of the cutting control box 12 away from the T-shaped swing arm 10, and a protective cover 14 is provided between the cutting disk 13 and the cutting control box 12, and the cutting disk 13 is in contact with the metal roof eaves 2. The cutting control box 12 is assembled with the cutting mounting beam 11 through the clamp, so that when the cutting control box 12 needs to be replaced, it is convenient for disassembly and maintenance. At the same time, the setting of the protective cover 14 can reduce the impact of cutting sparks on the operator.

[0035] The auxiliary connecting seat 15 is vertically fixed to the upper end of one side of the cutting mounting frame 8 by bolts. The upper end of the auxiliary connecting seat 15 is an arc-shaped structure. The virtual axis of one side of the arc-shaped structure of the auxiliary connecting seat 15 is coaxial with the virtual axis of the cross bar of the T-shaped swing arm 10. A guide slot 16 is penetrated on one side of the auxiliary connecting seat 15. The lower pressure rod of the T-shaped swing arm 10 movably penetrates the guide slot 16. The upper end of the lower pressure rod of the T-shaped swing arm 10 is provided with a first arc rod 17. The first arc rod 17 movably penetrates one side of the guide slot 16. A transfer slot is provided at the lower end of the auxiliary connecting seat 15. The transfer slot penetrates one side of the auxiliary connecting seat 15 and is provided with an input connector 23. The lower end of the auxiliary connecting seat 15 is connected to the transfer slot and is provided with an arc-shaped piston slot 20. A spring slot 19 is provided on the side of the guide slot 16 close to the arc-shaped piston slot 20. The lower end of the pressing rod of the T-shaped swing arm 10 is placed in the guide slot 16 and is provided with a second arc rod 18. One side of the second arc rod 18 is movable through the spring slot 19 and inserted into the arc piston slot 20 and is sleeved with a piston 22. The second arc rod 18 is placed in the spring slot 19 and is sleeved with a support spring 21 on one side. The T-shaped swing arm 10 can be rotated and guided by the auxiliary connecting seat 15. Before cutting, the walking route of the movable base 3 is determined first, and then the cutting control box 12 is started to make the cutting disc 13 rotate at a high speed. Then the T-shaped swing arm 10 rotates along the reference bearing seat 9 and the guide slot 16, and the cutting disc 13 drops to the lowest position to cut the metal roof eaves 2. Under the elastic support of the support spring 21, the cutting disc 13 will not contact the metal roof eaves 2 before cutting.

[0036] The heights of the cutting mounting frame 8 and the insulating edge-welding wheel 7 can be adjusted by bolts, and the adaptability is strong.

[0037] A pipe groove is provided in the second arc rod 18, which passes through the T-shaped swing arm 10 and the cutting installation beam 11. A delivery pipe 28 is inserted in the pipe groove. One side of the delivery pipe 28 is connected to the input joint 23 through a transfer groove. A three-way joint is provided on one side of the delivery pipe 28 inserted into the cutting installation beam 11. Spray heads 29 are respectively connected on both sides of the three-way joint through hoses. The spray head 29 passes through one side of the plug-in protective cover 14, and the spray head 29 is tilted to point to the cutting disk 13. When the input joint 23 delivers high-pressure water or high-pressure gas into the transfer groove, the high-pressure water or gas enters the two spray heads 29 from the delivery pipe 28 respectively, and then sprays on the junction of the cutting disk 13 and the metal roof eaves 2 to process the heat generated by the cutting and improve the cutting service life.

[0038] In this embodiment:

[0039] Embodiment 2: On the basis of embodiment 1, the auxiliary connecting seat 15 is provided with telescopic grooves 25 on both sides of the guide slide 16, and one side of the two telescopic grooves 25 is movably inserted with a limit block 26, and one side of the limit block 26 extends out of the telescopic groove 25. The lower pressure rod of the T-shaped swing arm 10 passes through the guide slide 16 and is horizontally provided with a matching positioning block 24. The two sides of the matching positioning block 24 are respectively abutted against the side of the two limit blocks 26 extending out of the telescopic groove 25. A spring guide rod is provided at the center of one side of the limit block 26 located in the telescopic groove 25. The spring guide rod movably passes through the auxiliary connecting seat 15, and the spring guide rod is sleeved on one side of the telescopic groove 25. A reset spring 27 is provided, and the side of the limit block 26 away from the matching positioning block 24 is an inclined structure. When the T-shaped swing arm 10 is not cutting, the cutting disk 13 is in a high position under the elastic support of the support spring 21. When the cutting control box 12 starts the cutting disk 13 to rotate at high speed and prepare for cutting, the lower pressure rod of the T-shaped swing arm 10 descends along the guide slot 16. At this time, when the two matching positioning blocks 24 encounter the limit block 26, the limit block 26 is pushed into the telescopic slot 25, and then the limit block 26 pops out under the action of the reset spring 27 to maintain the cutting position of the T-shaped swing arm 10 and the cutting disk 13 for self-positioning.
